Nano antibacterial cov ntaub ntawv yog ib yam ntawm cov ntaub ntawv tshiab nrog antibacterial zog.Tom qab qhov tshwm sim ntawm nanotechnology, cov tshuaj tua kab mob tau npaj rau hauv nano-scale antibacterial agents los ntawm qee txoj hauv kev thiab cov tswv yim, thiab tom qab ntawd npaj nrog qee cov tshuaj tua kab mob rau hauv cov khoom siv tshuaj tua kab mob.

Classification ntawm nano antibacterial cov ntaub ntawv

1. Cov khoom siv hlau nano antibacterial

Cov hlau ions siv nyob rau hauv inorganic nano antibacterial cov ntaub ntawv yognyiaj, tooj liab, zincthiab cov zoo li uas muaj kev nyab xeeb rau tib neeg lub cev.
Ag + yog tshuaj lom rau prokaryotes (cov kab mob) thiab tsis muaj tshuaj lom rau cov hlwb eukaryotic.Nws lub peev xwm los tiv thaiv kab mob yog qhov muaj zog tshaj plaws ntawm ntau cov hlau ions uas tuaj yeem siv tau zoo.Nano nyiaj muaj zog tua cov kab mob ntau yam.Vim nws tsis muaj tshuaj lom, dav-spectrum thiab zoo antibacterial zog, nano silver-based inorganic antibacterial cov ntaub ntawv tam sim no dominate inorganic antibacterial cov ntaub ntawv thiab yog dav siv nyob rau hauv cov khoom kho mob, pej xeem textiles thiab cov khoom siv hauv tsev.

2. Photocatalytic nano antibacterial cov ntaub ntawv
Photocatalytic nano antibacterial cov ntaub ntawv xa mus rau ib chav kawm ntawm semiconductor inorganic cov ntaub ntawv sawv cev los ntawm nano-TiO2, uas muaj photocatalytic zog, xws li nano-TiO 2, ZnO, WO 3, ZrO2, V2O3 ,SnO2, SiC, thiab lawv cov composites.Nyob rau hauv cov nqe lus ntawm cov txheej txheem thiab cov nqi kev ua tau zoo, nano-TiO2 muaj qhov zoo ntawm ob peb lwm cov khoom siv tshuaj tua kab mob photocatalytic: nano-TiO2 tuaj yeem tsis tsuas yog cuam tshuam cov kab mob fecundity, tab sis kuj tua cov txheej txheej ntawm cov kab mob, nkag mus rau hauv cov cell membrane, ua kom cov kab mob tsis zoo. kab mob, thiab tiv thaiv cov pa phem thib ob los ntawm endotoxin.

3. Inorganic nano antibacterial cov ntaub ntawv hloov nrog quaternary ammonium ntsev

Xws li cov khoom siv tshuaj tua kab mob feem ntau yog siv rau hauv intercalated nano-antibacterial khoom montmorillonite, nano-antibacterial khoom nano-SiO2 hais nrog grafted qauv.Inorganic nano-SiO2 particles yog siv raws li doping theem nyob rau hauv cov yas, thiab tsis yooj yim tsiv teb tsaws thiab precipitated los ntawm yas qhwv, thiaj li hais tias cov antibacterial yas muaj zoo thiab mus ntev antibacterial.

4. Composite nano antibacterial cov ntaub ntawv
Tam sim no, feem ntau cov ntaub ntawv nano-antibacterial siv ib qho khoom siv nano-antibacterial, uas muaj qee yam kev txwv.Yog li ntawd, tsim thiab tsim cov khoom siv tshuaj tua kab mob tshiab nrog kev ua kom tsis muaj menyuam sai thiab muaj txiaj ntsig tau dhau los ua ib qho tseem ceeb rau kev tshawb fawb tam sim no ntawm kev nthuav dav nanotechnology.

Daim ntawv thov tseem ceeb ntawm nano antibacterial cov ntaub ntawv
1. Nano antibacterial txheej
2. Nano antibacterial yas
3. Nano antibacterial fiber ntau
4. Nano antibacterial ceramics
5. Nano tshuaj tua kab mob hauv tsev cov ntaub ntawv

Nano antibacterial cov ntaub ntawv muaj ntau yam zoo sib txawv ntawm macroscopic composite cov ntaub ntawv, xws li kub kub tsis kam, yooj yim mus use, ruaj khov khoom, antibacterial spectrum ntev thiab kev nyab xeeb, ua nano antibacterial ntaub ntawv lug siv nyob rau hauv lub tsev cov ntaub ntawv, ceramics, anitary ware, textiles, plastics thiab ntau lwm cov teb.Nws ntseeg tau tias nrog kev tshawb nrhiav kev tshawb fawb tob tob, cov ntaub ntawv nano-antibacterial yuav ua lub luag haujlwm tseem ceeb hauv ntau yam xws li tshuaj, kev siv txhua hnub, tshuaj lom neeg kev lag luam thiab cov khoom siv hauv tsev.
